Re: Where is the first entry point for linux-mips boot?

[Marc Karasek <marc_karasek@ivivity.com>]

The firmware or bootloader.  For some examples of this look at redboot
from RedHat or yamon (yet another monitor) from MIPS (I think).  

Keep in mind these will prob require a seperate cross-compiler.  I have
yet to test compiling a boot monitor with linux gcc cross compiler.  You
can get one from either MIPS or Algorythmics (www.algor.co.uk).  I have
used both of these to build both of the above monitors.  

Any other questions, email me..
